SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 511,030, dated-December19, 1893.

Application filed November 25, 1892, Serial No. 453,091. (No model.)

T0 on whom it may concern:

Be it known that I, JOHN NICHOLAS STALL- INGS, residing at High Point,in the county of Guilford and State of North Carolina, have inventedcertain new and useful Improvements in Sash-Balances, of which thefollowing is a specification.

My invention refers more particularly to that class of sash balances inwhich the upper and lower sashes are connected in such a manner as tocounterbalance each other, and it has for its object to provide inconnection with such balanced sashes, suitably arranged mechanismwhereby the two sashes can be readily connected to operate in unison, ordisconnected, so that they can be operated independently.

The invention consists in the peculiar combination and novel arrangementof parts as described in the specification and particularly pointed outin the claims, reference being bad to the accompanying drawings, inwhich Figure 1 is a perspective view of a window, with my improvementsapplied. Fig. 2 is a sectional elevation of the same taken on the line22 in Fig. 3. Fig. 3 is a transverse vertical section thereof, on theline 33, Fig. 2. Fig. 4 is a detail view hereinafter referred to.

Referring to the accompanying drawings, A indicates the window easing,which is of the usual construction; B the upper, and O the lower sash,which sashes are supported on th e sash ropes D, one end cl of each ofwhich is connected to the upper sash, while the opposite ends of suchropes are connected with the lower sash in the manner most clearly shownin Figs. 1 and 2. By reference to such figures it will be noticed thatthe free ends (2' of the ropes D after they pass over the supportingsheaves E, extend down to the rear of the inner guide strips F, suchstrips being grooved on their rear faces as at f, such grooved stripsforming ways for the ropes, and entirely incasing the same; thereby notonly protecting such ropes, but also holding them in their properposition. The lower halves of the beads or strips F are slotted on theirfront faces as at f to receive the ends 9 of the combined connecting andpull bar G, such ends being connected to the lower ends of the ropesections d. By this construction it will be ob served that the pull rodis always held from any lateral (outward) movement, as its ends areguided by the slotted strips F, and as such ends are connected with therope ends cl inside such hollow strips F, it is manifest that the dangerof the bar becoming disconnected from the sash rope is entirely avoided.

Upon the lower end of the lower sash O are pivotal lugs 11 (see Fig. 6)which, when closed in, are out of the path of the vertical movement ofthe pull bar G, but when operated outward, as shown in Figs. 1 and 3,form stops which the bar G engages as shown. When such lugs H are turnedoutward as stated, it will be readily seen that the upper and lowersashes become connected, they balancing each other. It is thereforeobvious that by pushing the rod G upward, the upper sash will, belowered in proportion to the elevation of the lower sash, and by pullingsuch rod down, the upper sash will be raised while the lower sash willdrop by gravity, it being obvious that as such sashes counterbalancethey will remain at any position to which they maybe adjusted, so longas they are connected in the manner stated. hen it is desired to operatethe upper sash independent of the lower sash, the pivotal lugs 11 areclosed inward as shown in dotted lines in Fig. 4 which will al low for afree movement of the upper sash, which movement is regulated by the pullupon the bar G, and after such sash is adjusted as desired it may beheld in place by a suitable lock bolt J From the foregoing descriptiontaken in connection with the drawings it will be noticed that verysimple and effective means are provided for counter balancing thesashes, adjusting them together or independently, and housing the lowerend of the sash cord and the point of its connection with the operatingbar.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a sash balance, the combination of the upper and lower sashes, thesupporting sheaves, the cords having one end secured to the upper sash,a pull-bar secured to the opposite or free ends of such cords, andoperating in front of the lower sash, end guides for such bar, adaptedto hold such bar from outward movement, and stops on the lower sashprojected over such bar, all substantially as and for the purposedescribed.

2. In a sash balance,in combination, the upper and lower sashes, thesupporting" sheaves, the sash cords suspended therefrom, their rearportions connected to the upper sash, the front guide strips,havingrecessed rear faces adapted to receive the front sections of thesash cord, said strips slotted at their lower ends, a pull bar havingits ends extended in the slotted guide strips and connected to the freeends of the sash cords and the stops on the lower sash projected overthe said pullbar, all substantially as and for the purpose described.

3. In a sash balance, the combination with the upper and lower sashes,the sheaves, the

sash ropes, connected at one end to the upper sash, a pull-bar connectedat its ends with the free ends of the sash cord, end guides for suchpull-bar arranged to hold such bar from outward movement, and stops onthe lower sash projected over the pull-bar, said stops having a pivotalconnection with such sash whereby they can be closed inward against suchsash, and be out of the path of movement of the said pull-bar,substantially as and for the purposes described. a

In testimony whereof I affix my signature in presence of two witnesses.
